After seeing the fantastic results of this project, I'd be totally on board for a spoRved Mad Max 2. I've just bought the 1994 letterboxed laserdisc, so I can make a comparison with my existing 1991 capture and remake the audio if appropriate (it's tempting to do it over anyway, now that I have bitperfect facilities).
Not only would the original colours and audio be restored, but this would also be an ideal opportunity to fix the pesky WB logo in a more permanent way than my quick fix.
